PURPOSE: Method and apparatus of seawater desalination using solar heat are provided to increase heating efficiency by sequentially passing seawater introduced at low temperature through cooling pipe and heat recovery pipe, and improve condensation efficiency by keeping the surface of the cooling pipe cold. CONSTITUTION: In a desalination apparatus for desalting seawater using solar energy, the apparatus of seawater desalination comprises an intake unit(100) for introducing seawater containing salt; a filtering unit(200) for removing particle shaped materials such as floating matter in the seawater introduced; a vapor generator(300) in the inner upper space of which a cooling pipe(310) is formed, a collection pipe(320) having a certain slope is formed on the bottom of the cooling pipe(310), and which is consisted of a sealed housing, heated seawater is introduced into an inlet(330) formed at the lower part of the housing so as to induce generation of vapor; a heat exchanger(400) for increasing temperature of seawater flowing into a pipeline using latent heat of the seawater concentrated as seawater is passing through the vapor generator(300); and a solar heat collector(500) to an inlet formed at one side of which an outlet of a heat recovery pipe(410) positioned in the internal space of the heat exchanger(400) is extended so that the heated seawater is introduced into the solar heat collector(500), and which heats seawater using solar energy collected on a heat collection plate.
